Use of the Modified Ginzburg-Landau Equations in High Temperature Superconductors

Abstract

The modified Ginzburg-Landau equations are used to study some fundamental problems for the high temperature superconductors. The derivations of these fundamental equations are summarized and the layered features of the sample were taken into consideration and the relation between the coherence length and the separation distance of the layers. The domain wall energy, the maximum supercurrent and the parallel critical field of high temerature superconducting thin film were evaluated. Comparison with previous works is given
